我想将WebApp部署到应用引擎。此WebApp包含几个启动Google DataFlow作业的servlet。
我在本地运行我的WebApp（MVN Jetty：运行）并启动了调用Servlet的DataFlow作业。但是我正在努力将WebApp部署在App Engine中。
错误消息是：

问题可能在内存的限制（？）：

您知道这是哪个内存吗？这是我的战争文件，其中包含我需要运行填充超过629760KB内存的数据流管道的所有依赖项吗？您有什么想法可以看吗？
是的，看起来您的应用所需的比默认的0.6 GB或内存还要多，您需要在资源设置中配置更多内存：
MEMORY_GB
ram在GB中。您的应用程序请求的内存。每个CPU核心 需要总记忆力为0.9至6.5 GB，其中包括〜0.4 GB用于某些过程的开销（如更改）。到 计算请求的内存：memory_gb = number_cpu_cors * [0.9- 6.5] -0.4。对于上面指定2个内核的示例，您可以在1.4和12.6 GB之间请求。记忆总量 应用程序可用于运行时环境作为 环境变量 GAE_MEMORY_MB 。
